Claude Code can withdraw that host's tools, for example when it disconnects. When Claude now tries to use one of those tools, the lookup returns a `host_offline` error that includes the reason the tools were withdrawn. Before, it returned a generic offline message or `unknown_host`.\n\nThis does not apply to a host that is still connecting.\n\n**Why**\n\nWhen a remote or paired machine drops out, the error now tells you why.\n\n- Area: Remote Tools\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
